Products Description

Starting Resistor is a dedicated current-limiting component for the startup phase of electrical equipment, widely applied to motors, frequency converters, high-power electronic control devices and other equipment. Equipment generates severe inrush current the moment it is powered on, which may damage circuits, electronic components and power supply systems. Thanks to its stable resistance characteristics, the resistor is connected to the circuit upon power-up to suppress surge current and raise voltage and current steadily. After the equipment runs normally, it will be automatically disconnected by switches without affecting regular operation. With a robust structure, strong shock resistance and controllable temperature rise, it is suitable for various high-power electrical applications. It is an essential accessory to ensure smooth equipment startup and extend the overall service life of machinery.

Application Scope

Hoisting Industry

Suitable for motor start control of various hoisting equipment. It limits starting current and ensures safe operation of motors and power supply systems.

Mining Machinery

Ideal for motor startup of mining hoists, crushers and other large mining equipment. It delivers smooth startup to reduce mechanical shocks and extend equipment service life.

Metallurgical Equipment

Well-suited for motor startup of rolling mills, winches and other metallurgical equipment. It lowers startup impacts and maintains continuous, stable production.

Chemical Industry

Used for startup control of various pump and fan motors in chemical plants. Its good corrosion resistance adapts to harsh on-site conditions in the chemical sector.

Notes

No Overload Operation

Never use this resistor with motors exceeding its rated power range. Overload operation will lead to overheating, burnout and potential safety hazards.

Ensure Adequate Ventilation

The installation location must be well ventilated for heat dissipation. Do not place the resistor in enclosed spaces, as this will cause damage due to overheating.

Moisture & Water Protection

Although corrosion-resistant, the product must not be immersed in water or exposed to long-term severe dampness, which will degrade insulation performance.
